Basin bang

A basin bang is when you bang your girlfriend or a random girl you just scored in a public washroom.

Usually it’s a quickie sex session in the washroom of a bar, club, brewery, restaurant or gym!

Mostly takes place on the basin or toilet seat.

“Where’s Rob and Jen? They’ve been gone for a long time”
“Oh... bet they’re having a basin bang”

“That basin bang screwed up my injured back, the seat was too low”

“That chick and me had a hot basin bang at the pub. She got stuck on the tap, it flooded and we had to call 9-1-1” !!
